IFrame highly adaptive solution

In the web development work, we will inevitably encounter the use of the iFrame label. Sometimes we need to make the iFrame height automatically adapt to the content height to prevent the appearance of the scroll bar, which is conducive to page beautification. Here is an example of using JavaScript to automatically adapt iFrame to the height.

Default Page

<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 

 

Subpage

<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 

The IFrame height on the Default page is not set.

<Script type = "text/javascript"> // obtain the label height and width var h = document. getElementById ("div "). offsetHeight; var w = document. getElementById ("div "). offsetWidth; // obtain the iFrame label var iframe = optional parameter parent.doc ument of the parent page. getElementById ("myFrame"); iframe. style. width = w + "px"; iframe. style. height = h + "px"; </script>

 

Write a function on the default page

For example

Function helloword (){

 

Alert ('Hello ');

}

 

Subpage call Method

Window. parent. helloword ();
